Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The pilot stated that he was turning from the downwind to the base leg of the traffic pattern when the airplane’s engine had a total loss of power. The pilot trimmed the airplane for its best glide speed and maneuvered the airplane toward the runway. However, the airplane impacted the airport’s perimeter fence, which resulted in substantial damage to the right wing. A postaccident examination revealed that the engine air inlet cowling ducting had separated from its attaching material, and the ducting tube slid into the engine air flow control box, blocking the carburetor’s air inlet.
NTSB Probable Cause
The failure of the airplane’s engine air inlet system resulting in a total loss of engine power.
Full Narrative
The pilot stated that he was just turning from the downwind to the base leg of the airport’s traffic pattern when the experimental airplane’s engine had a total loss of power. He trimmed the airplane for best glide speed and maneuvered the airplane toward the runway. The airport has a tall perimeter fence, which ran across the approach end of the intended runway. The airplane did not have sufficient altitude to clear the fence and impacted into it resulting in the right wing incurring structural damage before coming to a complete stop. The pilot exited the airplane uninjured. A post wreckage examination revealed that the engine air inlet cowling ducting separated from its attaching material, which caused the ducting tube to slide into the engine air flow control box; blocking the carburetor’s air inlet.
